IP addresses are a hidden treasure trove that many universities don’t realize they possess. This intangible asset could be the key to unlocking much-needed funds. Read more

Routing, Trust & RPKI
The routing protocols we rely on today were developed in a much friendlier environment. No doubt, no one anticipated they’d be in place more than 30 years later. But protocol developers anticipated networks would want some level of control. Read more
